LUBRICATOR.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application led February Z1, 1907. Serial No. 358,545.

To all whom it may concern:

Be it known that 1, JOHANNES THEoDoEE PEDEnsEN, a citizen of the United States, residing at Woodside, in the county of Queens, city and State of New York, have invented an Improvement in Lubricators, ofwhich the following is a specification.

My invention relates to force feed or power actuated oil feeding devices or lubricators adapted for supplying lubricating oil in regulatable quantities to various kinds of machines, 4especially motor vehicles, motor boats, etc., where high speed demands constant lubrication visually assured and apparent, and the same is an improvement upon the devices described and shown in Letters Patent granted to me May 15, 1906, No.

' 820,821, with the object of simplifying, compacting and increasing the efficiency of the devices of said patent.

The lubricating device of my present invention comprises 4essentially a series of oscillating cylinders in a suitable body-frame or support, a series of longitudinally movable pistons or plungers in said cylinders, means for imparting movement to said pistons and cylinders, a receptacle for oil within whichsaid parts are placed and supported, means at one end of said cylinder and pistons for drawing in the oil from the receptacle and forcing it to and through suitable sight feed devices, and means at the other ends of said cylinders or pistons for receiving the oil from the sight feed devices and forcing it to the desired parts of the machinery to be lubricated.

The parts to which power and rotation are communicated from the machinery are similar to similarly acting parts shown and described in my aforesaid patent.

In the drawing, Figure 1 is a vertical cross section and partial elevation and Fig. 2 a vertical longitudinal cross section and partial elevation showing the devices of my improvement; the section Fig. 1 being longitudinally of the oil receptacle and Fig. 2 being transversely of the oil receptacle. Fig. 3 is a sectional plan on the dotted line m, of Fig. 2. Fig. 4 is a vertical cross section at the dotted line y, y, of Fig. 2. Fig. 5 is a vertical cross section on the dotted line z, z, of Fig. 2. Fig. 6 is a sectional plan and Fig.

7.fan end elevation of a modified form of myl invention. y

The receptacle or reservoir for holding the oil and for inclosing the devices hereinafterV described is preferably composed of a fronty a, back al, ends a2 and a bottom portion as. This reservoir is broken off so that the top is not shown. This top or upper end may be of any desired form and will advantageously support the sight feed devices as shown in my aforesaid patent, and through which sight feed devices the oil passes where its progress dan be visually noted and the fact that lubricating oil is flowing to the parts to be lubricated will be apparent and visually assured.

b represents a` body frame of metal and b1 auxiliary frames each including a stem 2, a nut 3, the stem entering a slot 4 of the body frame b and the auxiliary frame by means of the clamping nut 3 being securely held to the body frame, said auxiliary frame having a flat under surface resting upon the flat surface of the body frame and the said body frame is made with end frames b2.

c represents a bracket having a base adapted to be secured to the upper surface of the body frame b and c1 c2 are bearing sleeves formed therewith and at right angles to and slightly off-set from one another.

d are a series of pipes entering the oil reservoirs through the bottom, secured thereto by clamping nuts. The upper ends of these pipes d are threaded and they enter alined apertures in the body portion. e represents other series of pipes threaded at their lower ends and entering apertures in the body frame in line with the corresponding pipes d. These pipes e pass up and are intended to pass through the cover from the receptacle into the sight feed devices that may be employed in connection with the devices of my present improvement and such as are shown and described in my aforesaid patent. These series of pipes d e serve as supports for the body frame b and auxiliary frames b1 and the end frames b2 in the receptacle,main taining thesame rigidly in the desired position and at a predetermined height from the bottom of the oil reservoir.

A shaft passes through a bearing f1 in the back al o the reservior and on the forward end of this shaft is a worm g; the said shaftf passing through the bearing sleeve c1 of the bracket c for support and gui-dance.

A worm-wheel Zt meshes with the worm g 'of the shaft f and the said worm-wheel is upon the shaft Ztl placed vertically and pass ing through the bearing sleeve c2 for support and guidance and at its upper end rising and being advantageously constructed as shown in my aforesaid patent, in which the duplicate of this shaft passes through the cover and is shown as adapted to be provided with a manually actuated crank whereby the said shaft may be rotated by hand. In fact in Fig. 1 the upper end of this shaft is shown as solid and adapted for connection with the crank. I employ a crank arm i secured on the lower end of the upright shaft Ztl below the bearing sleeve c2. This crank arm is slotted as shown in Figs. 1 and 2, and as will also appear by reference to the aforesaid patent.

A rock-shaft 7c is provided with a pin k1 entering and passing through the slot of the crank arm i. This rock-shaft is longitudi nally movable in the end frames b2 and it is given a turning or oscillating movement as well as a longitudinal movement by the rotation of the crank arm i and a movement imparted thereby to the pin Zcl, said pin being a series of apertures 5 and in opposite faces of the body frame b and auxiliary frames b1 and in line with one another I provide a series of tapering recesses which receive the tapering ends of the cylinders fm, and in the device of my improvement I may employ any number of cylinders forming a series, and one of the objects of making the auxiliary frames separate from the body frame and adjustable is to cause a close fitting taper bearing between the respective ends of the series of cylinders m and the tapering recesses in said parts receiving the same. These cylinders are longitudinally slotted each to receive a pin 6 and a piston Z fits each cylinder; the pin being fast in the piston and projecting beyond the cylinder into an aperture 5 of the rock-shaft ZC. These pistons are longitudinally movable or reciprocating and they oscillate with the oscillation of the cylinders; said movements being caused by the oscillation of the rockshaft ZC and its longitudinal movement. These cylinders and pistons form pump devices for drawing the oil from the reservoirs and forcing it through the sight feed devices and also for receiving the oil from the sight feed devices and forcing it to parts of the machinery to be lubricated.

Referring particularly to Figs. 2, 4 and 5, I provide a port.7 in one end of each cylinder with an adjacent opening and a second similar opening through a foot portion of the auxiliary frame b1 and an intake ipe o passing through the body frame Z) in l1ne with the first aforesaid port 7, and through the body frame I provide conduits 10 having portions at right angles to one another and discharge pipes c1 which enter the upper portion of the body frame and rise to pass through the cover and connect with sight feed devices such as I have shown and described in my aforesaid Letters Patent. At the other or left hand end of the cylinders m and with special reference to Fig. 5, I provide the ports 8 9. Fig. 5 shows the port 8 as alining with the port from the pipe d, and the port 9 as closed off from alinement with the pipe e. This represents one position of the oscillating cylinder and in its other osition the port 9 alines with the pipe e an the port 8 is closed off from the pipe d. Likewise referring to Fig. 4, this shows the port 7 alining with the opening from the pipe 0, and in its other position the port 7 will aline with the opening from the conduits 10.

A modification of the form of my invention shown in Figs. 6 and 7 illustrates an end of a cylinder m1 as closed by a perforated plug or disk m2; this cylinder being preferably received in a recess of the body frame. The plug or disk m2 is provided with two ports 11 and 12 and the body frame with ports 13 and 14 having portions at right angles to one another. Fig. 7 shows one position of the oscillating cylinder in which the port 11 is concentric to the port 13 and the port 12 offset from the port 14. In the other position of this cylinder m1 the port A12 will be concentric to the port 14 and the port 11 closed off from the port 13.

I have hereinbefore generally described the operation of the device of my present invention with reference to the parts thereof, that is to say, the rotation of the shaft f and the worm g turns the worm-wheel h and the shaft in the slotted crank arm t', the pin 751 on the rock-shaft acting by the rotation of the crank arm fZ and these parts acting upon the pin 6 in the apertures 5 of the rock-shaft impart a reciprocating movement to the series of pistons Z and oscillating movements to both the series of pistons and the series of cylinders so -that in the position shown in Fig. 2 the oil from the receptacle is drawn by the pipe o through the port 7 into the right hand ends of the cylinders m and at the other end of said cylinders the oil is forced through the port 8 and by the pipes CZ to the machinery to be lubricated. With the movement of the pistons Z in the opposite directions and the turning movement of the cylinders the ports 7 aline with the openings to the conduits 10 and the portsQ aline with the openings to the pipes e and the oil in the right hand end of the cylinders, Fig. 2, is

`forced by the conduits 10 into the sight feed devices, returning by the pipes e, through the ports 9 into the chambers in the opposite ends of the cylinders m, so that when the pistons move again in the opposite direction and the cylinders oscillate the ports are brought again into the position shown in Figs. 4 and 5, in which oil is drawn in from the receptacle and forced by the pipes d to the machinery to be lubricated.

It is sometimes necessary to construct a lubricating device adapted to force a large number of streams of oil to many distant laces for lubricating parts of machinery and 1t is necessary to put this lubricating device into as small a compass as possible, and the device of my present invention is adapted to be put into a very much smaller compass than the devices of my hereinbefore named patent and this comes about in a large measure because there is no reciprocating frame support with which the series of cylinders and pistons move, for from the foregoing it will be apparent that the only movable part in the present case is the rock-shaft 7e, consequently the series of cylinders and their pistons in the stationary body frames can be placed as close together as is consistent with the independent movement of each g Figs. 1 and 2 of the drawing illustrate that the series of pipes e and o1 are in separate lines and staggered with reference to one another in order to be more compact.

I have herein shown and described a series of oscillating cylinders and a series of oscillating and reciprocating pistons within the cylinders and means for operating the same because such series will usually be employed in devices of this character for the reason that it is advantageous to force lubricating oil from a source of supply to numerous adjacent or nearby places for the lubrication of machinery and to do the same automatically. These devices may be employed and this act performed regardless of whether sight feed devices are employed for visually denoting the flow of the lubricating material or not. l Furthermore,V these devices are of small size and the series can be put into a small compass. It is obvious however, that the structure of my invention is equally adapted for forcing liquid or Huid in regulatable quantities from the source of supply. It is also obvious that the proportions of the parts are only questions of degree and that the same construction of greatly exaggerated size may be employed singly or in series actuated in the same or substantially the same manner for the purpose of forcing liquid or fluid from a source of supply to a source of use or predetermined point, and from this it will be apparent that the features of my invention are broader than the series of devices.
